Embodiment one

Reference picture 1, the flow chart of the method for the calibration value of the renewal mobile terminal of the embodiment of the present invention one is shown, it is described Dual camera module is provided with mobile terminal, the dual camera module includes the first camera and second camera, described The method for updating the calibration value of mobile terminal specifically may include steps of：

Step 101, same destination object is shot by first camera and the second camera respectively, First uncalibrated image and the second uncalibrated image corresponding to obtaining.

Due to certain distance generally be present between two cameras in dual camera module, i.e. the photocentre of camera lens does not weigh Close, then when being taken pictures by two cameras to same object, the object is generally also difficult to be in two cameras simultaneously Center；And if when the optical axis of two cameras in dual camera module is not parallel, pass through two cameras pair The angle that same object is taken pictures also can be different.It that is to say, if the module tolerance of dual camera module changes, these Change can the position in the image that two cameras shoot to obtain or angle embody respectively according to same object.

Mobile terminal in use, in the dual camera module set by the mobile terminal, the phase of two cameras Relative angle between position, or the optical axis of two cameras be able to may also be changed, i.e., the dual camera module is real The module tolerance on border and default dual camera module tolerance calibration value are not consistent, so as to cause to be difficult to the figure obtained to shooting As being difficult to effective deviation compensation, shooting effect is poor.

Therefore, in order in order to subsequently being carried out more to the module tolerance calibration value of dual camera according to the obtained image of shooting Newly, to improve the accuracy of dual camera module tolerance calibration value, reduce and be difficult to be difficult to effectively the image that shooting obtains Deviation compensation possibility, improve shooting effect, destination object can be entered by the first camera and second camera respectively Row shooting, obtains the first uncalibrated image and the second uncalibrated image.

Destination object is used to obtain the first uncalibrated image and the second uncalibrated image, and the destination object can include plane The object of object or solid, such as, the reference object can be the 2D gridiron pattern pictures of standard.

First camera can be any one camera in dual camera module, such as, wrapped when in dual camera module When including main camera and secondary camera, the first camera can be main camera.

In order to ensure during the first uncalibrated image and the second uncalibrated image is obtained, destination object and camera in pairs Relative position and angle between module are not changed, and the first camera can be controlled to obtain the first uncalibrated image, control simultaneously Second camera processed obtains the second uncalibrated image.

Default dual camera module tolerance calibration value can include translation tolerance calibration value and rotate in tolerance calibration value It is at least one.Wherein, translate tolerance calibration value and be used to illustrate that the relative position between the first camera and second camera to become Change, rotate the relative angle change that tolerance calibration value is used to illustrate between the first camera and the optical axis of second camera.Can be with The module tolerance of dual camera module is demarcated before current time, obtains the dual camera module tolerance calibration value, And store the dual camera module tolerance calibration value into the storage of dual camera module, such as before mobile terminal dispatches from the factory Or before dual camera module dispatches from the factory, the module tolerance of dual camera module is demarcated, and obtained by calibrating pair is imaged Head mould group tolerance calibration value is stored.

In embodiments of the present invention, it is preferred that in order to improve the figure for getting the first uncalibrated image or the second uncalibrated image As quality, mobile terminal can be fixed by equipment such as tripods.

In embodiments of the present invention, it is preferred that get the first uncalibrated image and the second uncalibrated image to improve Picture quality, the shooting environmental shot by the dual camera module to destination object can be adjusted, such as, ring Border colour temperature 5000K (Kelvin), intensity of illumination are more than or equal to 500lux (Lux), uniform lighting etc..

Step 102, based on default dual camera module tolerance calibration value, to first uncalibrated image or described second Uncalibrated image carries out deviation compensation processing.

In order to determine whether the current module tolerance of dual camera changes, default double camera module tolerance calibration values Whether effective deviation compensation processing can be carried out to the image that shooting obtains, default dual camera module tolerance can be passed through Calibration value carries out deviation compensation processing to the first uncalibrated image or the second uncalibrated image, after being handled according to deviation compensation Uncalibrated image and the uncalibrated image for not compensating processing, update double camera module tolerance calibration values.

It can obtain the configuration parameter of the dual camera module from the storage of dual camera module, including each camera Pixel, focal length, focal length ratio, f-number, double parallax ranges (the distance between photocentre of i.e. two cameras) and default taken the photograph Dual camera module tolerance calibration value, by default bias compensation, based on the dual camera module tolerance calibration value, Deviation compensation is carried out to uncalibrated image according to the pixel of each camera, focal length, focal length ratio, f-number, double parallax ranges etc. of taking the photograph Processing.

Bias compensation is used to carry out deviation compensation processing to image.

Step 103, the uncalibrated image of processing is not compensated based on the uncalibrated image after deviation compensation processing and, to described Dual camera module tolerance calibration value is updated.

Due to having carried out deviation compensation processing to the first uncalibrated image or the second uncalibrated image, it is possible to by destination object Position or angle in uncalibrated image after deviation compensation processing, the position or angle in uncalibrated image with not compensating processing Degree is compared, so that it is determined that whether dual camera module tolerance calibration value can obtain image to shooting carries out effective compensation, And whether dual camera module tolerance calibration value is updated.

If position or angle in uncalibrated image of the destination object after deviation compensation processing, with not compensating processing Uncalibrated image in position or angle deviation be present, then illustrate default dual camera module tolerance calibration value and actual mould Group tolerance is inconsistent, i.e., whether dual camera module tolerance calibration value can fail to obtain shooting image progress effective compensation, Can be according to position or angle in uncalibrated image of the destination object after deviation compensation processing, with not compensating the mark of processing Determine the deviation between position or the angle in image, dual camera module tolerance calibration value is updated.

Wherein it is possible to according to destination object at least one pixel point coordinates in above two uncalibrated image respectively, come true Set the goal and whether there is deviation between position or angle of the object in above two uncalibrated image.Such as destination object difference The pixel point coordinates of same point in above two uncalibrated image, or, destination object is respectively in above two uncalibrated image The distance between multiple pixel point coordinates.

Can be according to position or angle in uncalibrated image of the destination object after deviation compensation processing, with not compensating The deviation between position or angle in the uncalibrated image of processing, dual camera module tolerance calibration value is increased or subtracted It is few, so that dual camera module tolerance calibration value is consistent with the module tolerance that dual camera module is actual.

In embodiments of the present invention, for being provided with the mobile terminal of dual camera module, can be taken the photograph respectively by first As head and second camera the first uncalibrated image of acquisition and the second uncalibrated image, according to default dual camera module tolerance mark Definite value carries out deviation compensation processing, the demarcation after then being handled according to deviation compensation to the first uncalibrated image or the second uncalibrated image Image and the uncalibrated image for not compensating processing, determine the inclined of the image that dual camera module tolerance calibration value obtains to shooting Poor compensation effect, and then dual camera module tolerance calibration value is updated, improve dual camera module tolerance calibration value Accuracy, improve shooting effect.

Embodiment two

Reference picture 2, the flow chart of the method for the calibration value of the renewal mobile terminal of the embodiment of the present invention two is shown, it is described Dual camera module is provided with mobile terminal, the dual camera module includes the first camera and second camera, described The method for updating the calibration value of mobile terminal specifically may include steps of：

Step 201, when destination object is in the center of the camera lens of first camera, the mobile terminal point Same destination object is not shot by first camera and the second camera, obtains corresponding first demarcation Image and the second uncalibrated image.

For the ease of position or angle in the follow-up uncalibrated image for calculating destination object after deviation compensation processing, and not The deviation between position or the angle in the uncalibrated image of processing is compensated, and then improves and dual camera module tolerance is demarcated The efficiency that value is updated, during the center for the camera lens that can be in the first camera in destination object, obtain the first demarcation Image and the second uncalibrated image.

Shooting image can be treated by the first camera and carries out preview, and detects whether the reference object is located in camera lens In optical center.Wherein, destination object, which is in optical center and refers to the center of the destination object, is in the optical axis of the first camera. For example, as shown in figure 3, destination object is the 2D gridiron pattern pictures of standard, can be taken the photograph full of first the gridiron pattern picture is placed in the middle As the camera lens of head, and the four of the gridiron pattern picture while with the first cam lens four while overlap when, determine at the destination object In the center of the camera lens of the first camera.

Certainly, in actual applications, can be to be captured by the first camera preview by user or person skilled Image, shooting angle is adjusted, the destination object is in the optical center of the first camera.

Mobile terminal is respectively by way of the first camera and second camera are shot to destination object, Ke Yican See it is foregoing in associated description, no longer repeat one by one herein.

In embodiments of the present invention, it is preferred that for the ease of determining whether destination object is in the camera lens of the first camera Center, the destination object is rectangular image, for example, it is foregoing in standard 2D gridiron pattern graph cards.

Step 202, the mobile terminal is based on default dual camera module tolerance calibration value to second calibration maps As carrying out deviation compensation processing.

Due to foregoing when obtaining the first uncalibrated image and the second uncalibrated image, destination object is in the mirror of the first camera The center of head, so for the ease of subsequently carrying out the second uncalibrated image after compensation deals and the first uncalibrated image pair Than, position or angle in second uncalibrated image of the destination object after the first uncalibrated image and compensation deals whether one Cause, and then whether accurate judgement dual camera module tolerance calibration value effectively carries out effective deviation compensation to the second uncalibrated image, Default dual camera module tolerance calibration value can be based on deviation compensation processing is carried out to the second uncalibrated image.

Default dual camera module tolerance calibration value can include the first translation tolerance calibration value and first and rotate tolerance It is at least one in calibration value, it is possible to which that deviation benefit is carried out to second uncalibrated image by the first translation tolerance calibration value Processing is repaid, and/or, rotate tolerance calibration value by first and deviation compensation processing is carried out to second uncalibrated image.

Wherein, the first translation tolerance calibration value can include x-axis translation tolerance calibration value and y-axis translation tolerance calibration value, First, which rotates tolerance calibration value, can include x-axis rotation tolerance calibration value and y-axis rotation tolerance calibration value.

Certainly, in actual applications, if being when destination object is in the centre bit of the camera lens of second camera in foregoing , here can be with when putting, and obtaining the first uncalibrated image and the second uncalibrated image by the first camera and second camera respectively Deviation compensation processing is carried out to the first uncalibrated image.

Step 203, the mobile terminal is based on second mark after first uncalibrated image and deviation compensation processing Determine image, calculate at least one in shifting deviation and rotational variations.

Because the actual module tolerance of dual camera module may and differ with dual camera module tolerance calibration value, wrap Include shifting deviation and rotate tolerance in it is at least one, so in order to dual camera module tolerance calibration value carry out more Newly, the accuracy of dual camera module tolerance calibration value is improved, so as to shoot obtained image to dual camera exactly Deviation compensation is carried out, the effect by dual camera shooting image is improved, can calculate in shifting deviation and rotational variations extremely It is few one.

Shifting deviation is the difference between the actual translation tolerance of dual camera module and the first translation tolerance calibration value, is turned Dynamic deviation is the difference between the actual rotation tolerance of dual camera module and the first rotation tolerance calibration value.

In embodiments of the present invention, due to when in the absence of shifting deviation, after the first uncalibrated image and deviation compensation In second uncalibrated image, the center of image corresponding to destination object and the center superposition of the first uncalibrated image, and and deviation compensation The center superposition of the second uncalibrated image afterwards, otherwise, the center of image corresponding to destination object and the center of the first uncalibrated image Overlap, and it is misaligned with the center of the second uncalibrated image after deviation compensation, it that is to say, shifting deviation can pass through destination object The position in the second uncalibrated image after the first uncalibrated image and deviation compensation is embodied respectively at the center of corresponding image, institute With for shifting deviation, in order to which shifting deviation is fast and accurately calculated, it is preferred that the destination object can be determined First pixel point coordinates of the center in first uncalibrated image, and the center of the destination object are handled in deviation compensation The second pixel point coordinates in second uncalibrated image afterwards, based on the first pixel point coordinates and second pixel Coordinate, determine the shifting deviation of the dual camera module.

By taking the first uncalibrated image as an example, position of the destination object in the first uncalibrated image can be determined by image recognition Put, and the center of destination object, so that it is determined that pixel point coordinates of the center of destination object in the first uncalibrated image.

Wherein, shifting deviation can include x-axis shifting deviation and y-axis shifting deviation.The x coordinate of second pixel point coordinates with The difference of the x coordinate of first pixel point coordinates, as x-axis shifting deviation, the y-coordinate and the first pixel of the second pixel point coordinates The difference of the y-coordinate of coordinate, as y-axis shifting deviation.

X-axis shifting deviation can be expressed as Δ X₁=x₀-x'₀, wherein, Δ X₁Represent x-axis shifting deviation, x₀Represent the second picture The x coordinate of vegetarian refreshments coordinate, x'₀Represent the x coordinate of the first pixel point coordinates.

Y-axis shifting deviation can be expressed as Δ Y₁=y₀-y'₀, wherein, Δ Y₁Represent y-axis shifting deviation, y₀Represent the second picture The y-coordinate of vegetarian refreshments coordinate, y'₀Represent the y-coordinate of the first pixel point coordinates.

Certainly, because the first uncalibrated image and the second uncalibrated image are the camera lens that image to be captured is in the first camera Center claps to obtain, i.e., the center of destination object necessarily overlaps with the center of the first uncalibrated image, so, it will can shoot Pixel coordinate to the central point of image is set as (0,0), and in this case, x-axis shifting deviation can be expressed as Δ X₁= x₀, y-axis shifting deviation can be expressed as Δ Y₁=y₀。

For example, mobile terminal includes main camera (the first camera) and secondary camera (second camera), destination object For the 2D gridiron pattern graph cards of standard, shooting obtains the first uncalibrated image as shown in figure 4, the second calibration maps after deviation compensation processing As shown in Figure 5.Wherein, in Fig. 4, the image of gridiron pattern graph card is full of whole first uncalibrated image between two parties, in Figure 5, by In the visual angle of secondary camera extensively in main camera, so the image of gridiron pattern graph card only occupies the part in the second uncalibrated image Region.It is (40,60) to obtain pixel point coordinates of the center of gridiron pattern graph card in the first uncalibrated image by image recognition, The pixel point coordinates in the second demarcation after deviation compensation processing is (45,66).Or in the examples described above, gridiron pattern graph card Pixel point coordinates of the center in the first uncalibrated image be (0,0), the pixel in the second demarcation after deviation compensation processing Point coordinates is (5,6).X-axis shifting deviation is 45-40=5, and y-axis shifting deviation is 66-60=6.

In addition, in actual applications, shifting deviation can be expressed asThat is the first picture The distance between vegetarian refreshments coordinate and the second pixel point coordinates.

In embodiments of the present invention, due to when in the absence of rotational variations, destination object each side in the first uncalibrated image Ratio between the length of side, the ratio between each side length of side in the second uncalibrated image of the destination object after deviation processing is consistent, So for rotational variations, it is preferred that can determine in second uncalibrated image of the rectangular image after compensation deals The length of side on each side, based on the length of side on each side, determine the rotational variations of the dual camera module.

, can be by image recognition, to determine the image of destination object in the first calibration maps by taking the first uncalibrated image as an example Each side as in, and the length of side on each side.

Wherein, rotational variations can include x-axis rotational variations and y-axis rotational variations.The image of destination object is in the first mark Determine in image, parallel to the ratio of two side length of sides of x-axis, with the second mark of the image of destination object after deviation compensation processing Determine in image, parallel to the difference between the ratio of two side length of sides of x-axis, as x-axis rotational variations.The image of destination object In the first uncalibrated image, parallel to the ratio of two side length of sides of y-axis, the image with destination object is after deviation compensation processing The second uncalibrated image in, parallel to the difference between the ratio of two side length of sides of y-axis, as y-axis rotational variations.

X-axis rotational variations can be expressed asWherein, Δ X₂Represent x-axis rotational variations, x'₁And x'₂Table Show the image of destination object in the first uncalibrated image parallel to two side length of sides of x-axis, x₁And x₂Represent the image of destination object Parallel to two side length of sides of x-axis in the second uncalibrated image after deviation compensation processing.

Y-axis rotational variations can be expressed asWherein, Δ Y₂Represent y-axis rotational variations, y'₁And y'₂Table Show the image of destination object in the first uncalibrated image parallel to two side length of sides of y-axis, y₁And y₂Represent the image of destination object Parallel to two side length of sides of y-axis in the second uncalibrated image after deviation compensation processing.

Certainly, from the foregoing it will be appreciated that when destination object is rectangle, such as during gridiron pattern graph card, the first uncalibrated image and second Uncalibrated image can be full of the camera lens of the first camera, and four sides of the destination object and the first camera between two parties in destination object Four sides of camera lens shoot to obtain when overlapping, so, x'₁And x'₂It is equal, and y'₁And y'₂Equal, therefore, x-axis rotational variations can be with It is expressed asY-axis rotational variations can be expressed as

For example, in Figure 5, measurement obtains x₁For 90, x₂For 100, thenΔX₂ForMeasurement obtains y₁ For 60, y₂For 62, thenΔY₂For

Step 204, the mobile terminal is at least one in the shifting deviation and the rotational variations, and judgement is It is no that dual camera module tolerance calibration value is updated.

Due to when deviation between the actual module tolerance of dual camera module tolerance calibration value and dual camera being present, but should When deviation is in certain limit, because human eye is to the limited sensitivity of image detail, by bias compensation to shooting To image compensate after, for human eye, have been able to reach preferable visual effect, i.e. deviation compensation effect is preferable. So in order to the module tolerance according to storage to the deviation compensation effect of image still preferably in the case of, be reduced or avoided pair Whether the module tolerance of storage is updated, to save cost, it can be determined that module tolerance is updated.

In embodiments of the present invention, it is preferred that judge to be updated dual camera module tolerance calibration value to improve Accuracy, mobile terminal may determine that whether the shifting deviation is more than shifting deviation threshold value, if the shifting deviation is big In the shifting deviation threshold value, then perform and described the described first translation tolerance calibration value is updated according to the shifting deviation The step of；And/or judge whether the rotational variations are more than rotational variations threshold value, if the rotational variations are more than described turn Dynamic deviation threshold value, then perform described the step of being updated according to the rotational variations to the described first rotation tolerance calibration value.

Shifting deviation threshold value or rotational variations threshold value can by being determined in advance to obtain, such as, receive numerical value of submission etc..

For example, shifting deviation threshold value can be 10, rotational variations threshold value can be

Because shifting deviation can include x-axis shifting deviation and y-axis shifting deviation, rotational variations can include x-axis and rotate Deviation and y-axis rotational variations, it is possible to respectively compared x-axis shifting deviation and y-axis shifting deviation with shifting deviation threshold value Compared with when at least one in x-axis shifting deviation and y-axis shifting deviation is more than shifting deviation threshold value, determining that shifting deviation is more than Shifting deviation threshold value.Similar, x-axis rotational variations and y-axis rotational variations are worked as into x compared with rotational variations threshold value respectively When at least one in axle rotational variations and y-axis rotational variations is more than rotational variations threshold value, determine rotational variations be more than rotate it is inclined Poor threshold value.

Certainly, in actual applications, can in order to further improve the accuracy for judging whether to be updated to module tolerance To set x-axis shifting deviation threshold value and y-axis shifting deviation threshold value respectively, so as to which x-axis shifting deviation, y-axis shifting deviation be distinguished Compared with corresponding threshold value, and when any one in x-axis shifting deviation and y-axis shifting deviation is more than corresponding threshold value, Determine that shifting deviation is more than shifting deviation threshold value.Similar, x-axis rotational variations threshold value and y-axis rotational variations can be set respectively Threshold value, so that by x-axis rotational variations, y-axis rotational variations respectively compared with corresponding threshold value, and in x-axis rotational variations and y Any one in axle rotational variations during threshold value, determines that rotational variations are more than rotational variations threshold value more than corresponding to.

Step 205, the mobile terminal is at least one in the shifting deviation and the rotational variations, to described Dual camera module tolerance calibration value is updated.

In order to ensure dual camera module tolerance calibration value is consistent with the actual module tolerance of dual camera module, improve The accuracy of dual camera module tolerance calibration value, so that it is guaranteed that carrying out the accuracy of deviation compensation to image, improve shooting effect Fruit, dual camera module tolerance calibration value can be updated.

The described first translation tolerance calibration value can be updated according to the shifting deviation, and/or, according to described turn Dynamic deviation is updated to the described first rotation tolerance calibration value.

If being updated to the first translation tolerance calibration value, shifting deviation and the first translation tolerance can be subjected to phase Add, so as to be updated to obtain the second translation tolerance calibration value to the first translation tolerance.Wherein it is possible to by x-axis shifting deviation and x Axle translation tolerance calibration value is added, and institute's value is the x-axis translation tolerance calibration value after updating；Accordingly, y-axis is put down Move deviation to be added with y-axis translation tolerance calibration value, institute's value is the y-axis translation tolerance calibration value after updating.

For example, it is -3 that the first translation tolerance calibration value, which includes x-axis translation tolerance calibration value, y-axis translation tolerance calibration value is 4, x-axis shifting deviation is 5, and y-axis shifting deviation is 6, then the x-axis translation tolerance calibration value after updating is -3+5=2, after renewal Y-axis shifting deviation calibration value is 4+6=10.It that is to say, the second translation tolerance calibration value is obtained after renewal includes x-axis translation tolerance Calibration value is 2, and y-axis translation tolerance calibration value is 10.

If being updated to the first rotation tolerance calibration value, rotational variations and first can be rotated tolerance calibration value It is added, so as to be updated to obtain the second rotation tolerance calibration value to the first rotation tolerance calibration value.Wherein it is possible to by x Axle rotational variations rotate tolerance calibration value with x-axis and are added, and institute's value is that the x-axis after updating rotates tolerance calibration value； Accordingly, y-axis rotational variations are rotated into tolerance calibration value with y-axis to be added, institute's value is that the y-axis after updating rotates public affairs Poor calibration value.

For example, the first rotation tolerance calibration value is including x-axis rotation tolerance calibration valueY-axis rotates tolerance calibration valueX-axis rotational variations areY-axis rotational variations areX-axis after then updating rotates tolerance calibration valueY-axis after renewal rotates tolerance calibration value It that is to say, obtain after renewal Two rotation tolerance calibration values include x-axis rotation tolerance calibration valueY-axis rotates tolerance calibration value

Certainly, in actual applications, efficiency is updated to dual camera module tolerance calibration value in order to improve, while The accuracy of dual camera module tolerance calibration value is improved, the accuracy compensated to the image of shooting is improved, is calculating To after shifting deviation and rotational variations, can not also judge whether to be updated dual camera module tolerance calibration value, but, It is directly at least one in the shifting deviation and rotational variations being calculated, dual camera module tolerance calibration value is carried out Renewal.

, can be by the dual camera module tolerance after renewal after being updated to dual camera module tolerance calibration value Calibration value is stored.

Step 206, the mobile terminal is not updated to the dual camera module tolerance calibration value.

For example, a kind of flow chart of the method for the calibration value for updating mobile terminal can be as shown in Figure 6.As shown in fig. 6, step Rapid 601, obtain the configuration parameter of dual camera module, including the pixel of each camera, focal length, focal length ratio, f-number, double take the photograph Parallax range, module tolerance etc.；Step 602, build demarcation environment, including standard 2D gridiron pattern graph cards be set, environment colour temperature with And intensity of illumination etc.；Step 603, shooting obtains the first uncalibrated image and the second uncalibrated image；Step 604, module tolerance is calculated Change, including according to the second uncalibrated image after the first uncalibrated image and deviation compensation, calculate shifting deviation and rotational variations；Step Rapid 605, judge whether to be updated dual camera module tolerance calibration value, shifting deviation and shifting deviation threshold value are compared Compared with, and by rotational variations compared with rotational variations threshold value, if shifting deviation is more than shifting deviation threshold value, and/or, rotate Deviation is more than rotational variations threshold value, it is determined that dual camera module tolerance calibration value is updated, performs step 606, otherwise It is determined that not being updated to dual camera module tolerance calibration value, step 607 is performed；Step 606, to dual camera module tolerance Calibration value is updated；Step 607, dual camera module tolerance calibration value is not updated.
